Because it looks to me that this is libc problem with fetestexcept. As far as
the compiler is concerned, GCC correctly decorates trapping instructions with
/sui and puts trap barrier to expected place:
...
jsr $26,($27),__nldbl_printf !lituse_jsr!5
ldah $29,0($26) !gpdisp!6
divs/sui $f3,$f2,$f0
trapb
...
